PROTECTED COMMERCIAL PAPER.

Y Specification of Letters Patent.

Patented Mar. 7, 19161 Application filed October 4, 1915. Serial No. 54,083.

To all whom it may concern.'

Be it known that I, ARTHUR E. MEYER, a citizen of the United States, residing at Chicago, in the co-imty of Cook and State of Illinois, have invented certain new and useful Improvements in Protected Commercial Papers, of which the following is a specification.

The present invention relates to .a means for treating commercial paper, such as bank checks, notes, etc., in a manner to prevent the alteration of any part thereof.

The principal objects of the invention are to provide a process for carrying out the above purpose, which can be .applied easily and quickly, and applied with equal efficiency irrespective of the manner in which the written portions of the paper are arranged.

A further object of the invention is to provide means whereby all of the written portions 0f the paper are protected against alteration.

The invention further consists in the features of construction and combination of parts hereinafter described and claimedt In the drawings: Figure l is a face view y of the bank check protected in accordance with the teachings of the present invention; and Fig. 2 is a longitudinal section of such check.

In the .art to which the present invention relates, there have been a variety of ways and means disclosed for treating commercial paper, so as to prevent an erasing of a portion thereof and a Subsequent alteration, or otherwise changing the tenor of the paper. But the methods now commonly employed necessitate the use of complex machinery and are not adapted to prevent erasures of all portions of the filled in or written part of the check, and are directed toward that portion wherein the amount is stated.

I consider it to be very advantageous to provide means for protecting all written portions of the paper, this principally by reason 0f the fact that such paper is ar ranged to bring the written portions into different relative arrangement and location,

and with the devices now used, of which I .am aware, a material written portion of the paper will not be protected in any way.

By the present invention, a protection of all of the written portions of the paper against alteration is provided for, irrespective of the manner in which said written portions may be arranged.

Referring now to the drawings, the invention is shown as applied to a bank check 3, which can be of suitable size and nature, and can be arranged, as to the printed and written matter thereon, in any way desired. After this check has been filled in, that is, the name of the payee and the amount written in, and signed by the payor, the paper is submitted to a treatment of any suitable mechanical appliance, which will place a series of corrugations 4C across the entire surface of the same at a single operation. By thus corrugating the entirey surface of the paper, not only is the means for insuring against alteration of the .amount quickly and easily applied, but all portions of the check or paper will be so treated. Consequently, there is no danger of leaving any important portion of the written part of the paper unprotected, nor to accomplish this need the written portion of the check be arranged in any particular manner. Therefore, irrespective of the arrangement of the written matter on the paper, or the form or character thereof, by corrugating the entire surface of the paper, the check is protected against alteration of any written portion, thus eliminating the danger of leaving certain portions eX- posed and unprotected, and eliminating any clerical error in placing the protection where it would be unavailing.

By so protecting the paper, in `accordance with the present invention, it is possible to obtain. the protection without the use of any complicated or expensive machinery. The protection can be obtained equally as well whether the matter inserted in the check is written by hand or upon the typewriter; and the operation which is required for protecting is of a nature which is very quickly and easily applied, entailing prac- Q L17/m53 tically no more Work than would be entions extending entirely across that portion tailed in the filling in of the check. of the paper Within the confines of Which I claim: Written matter is placed, substantially as A bank check or similar commercial padescribed. 5 per, comprising an unp'unctured body formed with regularly occurring corruga- Al'II-HQTRY E.
